Use the export command to mark a variable name for
automatic export to the environment of subsequent commands. All subsequent
commands use the variable name values as specified; unless you unset them
or exit multimode. If only the variable name is specified, subsequent commands
receive a value set in a previous assignment. If the export command is used
without any arguments, a list of all the exported variables and their values
is displayed. Exported shell environment variables set prior to invoking the
asadmin utility are imported automatically and set as exported variables within
asadmin. Unexported environment variables cannot be read by the asadmin utility.
Where: the export command lists the environment variables
that are set. In this case, the environment variables have been set to: the
host is bluestar, the port is 8000,
the administrator user is admin with an associated password,
and the prefix is server1.jms-service.
